Product Name: Contact Spring
Material: Beryllium Copper C1720R-1/2H, t:0.2mm
Key Points in Die Design:
Since the part is press-fitted into a pipe, special measures are required to achieve precise circularity.

Key Points in Press Processing:
As load management after heat treatment of the tip is crucial, strict dimensional control is essential during press processing.

At Kyowa Hearts, we specialize in micro, precision, and complex leaf spring processing.
We excel in manufacturing contacts and leaf springs for PC connectors and other electronic components.
Leaf spring processing requires a deep understanding of material properties, especially experience-backed data on springback behavior.

Once the drawing is completed, we start with prototyping. From 1 to 1000 pieces, using laser processing, wire EDM, etching, and bending with temporary dies for blanking.
For mass production, we utilize progressive dies to manufacture from 5,000 to over 1 million pieces—covering all production needs.
